<u>Answer:</u>
The stopping car has negative acceleration.
<u>Explanation:</u>
We know acceleration is the rate of change of velocity. That is
Acceleration(a) = ( Final velocity - Initial velocity )/ Time taken.
Here Final velocity = 0 km/h( car stops) and initial velocity = 30 km/h
So acceleration = (0-30)/time = -30/ time
Time is always positive , so -30/time is negative, so the stopping car has negative acceleration.
Answer:
graph 1
Explanation:
When it comes to a graph showing "constant acceleration," the line should be straight and upward <em>(positive acceleration) or </em>straight and downward <em>(negative acceleration).</em> The variables for acceleration are time and velocity. The independent variable (time) should be placed on the<em> x-axis</em> while the dependent variable (velocity) should be placed on the<em> y-axis.</em> As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. <u>They are also directly proportional to each other</u>. This is evident on the first graph.
V=IR, therefore when resistance is constant the voltage and current are directly proportional
